Abstract

Abstract A novel iridium (III) hydride complex, IrHCl (TIMP 3){HTIMP 3= tris [1- (diphenylphosphino)-3-methyl-1H-indol-2-yl] methane} was prepared and fully characterized in both the solid state and in solution. Chloride abstraction by silver cations provides a more reactive compound,[IrH (TIMP 3)][BF 4], which can react with pyridine (py) and phenylacetylene to yield the complexes [IrH (TIMP 3)(py)][BF 4] and [Ir (PhCH [ ...
